I wanted to add ARM CPU darwin to the CI but it seems that kerberos/001_auth fails on ARM CPU darwin.
OS:
Darwin admins-Virtual-Machine.local 21.6.0 Darwin Kernel Version 21.6.0: Wed Aug 10 14:26:07 PDT 2022; root:xnu-8020.141.5~2/RELEASE_ARM64_VMAPPLE arm64
Error message: Can't exec "kdb5_util": No such file or directory at /Users/admin/pgsql/src/test/perl/PostgreSQL/Test/Utils.pm line 338. [02:53:37.177](0.043s) Bail out! failed to execute command "kdb5_util create -s -P secret0": No such file or directory
It seems that kerberos is installed at the '/opt/homebrew/opt/krb5' path on ARM CPU darwin instances instead of the '/usr/local/opt/krb5' path.
I attached two patches: 0001-ci-Add-arm-CPU-for-darwin.patch is about adding ARM CPU darwin to the CI.
0002-fix-darwin-ARM-CPU-darwin-krb5-path-fix.patch is about fixing the error.
